This one puts Datum on your Home Screen, your wrist, your car and your Mac. HOME SCREEN WIDGETS, FREE Six of them, on iPhone and iPad. Log Entry tallies, taps or picks a value without opening the app. The other five show a tracker's latest value and trend, your recent trackers, a check-in, your logging streak, and a map of where you've logged. APPLE WATCH Log from your wrist. Turn the Digital Crown to set a number, or tap yes, no, or one of your options. CARPLAY Choose up to four number trackers in Settings › Data › CarPlay. Each becomes a button on the car screen that logs its default value in one tap, with the place and the weather if the tracker captures them. MAC Datum for Mac has a sidebar, menus, keyboard shortcuts and a right-click menu on every card. It stays in step with your iPhone and iPad through your own iCloud. ALSO NEW • Datum is now available in Spanish. • The cube in the corner is now a menu button: the Library, Connect a Source, Automations, Show Hidden and Settings, from any tab. • Settings has a Purchases tab with everything for sale, its price, and Restore. Still no subscriptions. • Export can make a Report: a PDF of your entries, with the count, average and range up top. • Place automations now record where they fired, on trackers that capture location. • Number trackers can total or average their entries. Counts and money add up over the period you're looking at. • Tally and tap pads work with measured units too: mL of water, km run, 50 lb hay bales. • On iPhone Duo, sheet buttons like Save and Cancel move into the side toolbar. FIXED • Changes from your other devices appear when iCloud delivers them, without a pull to refresh. • "Syncing from iCloud" shows only when there's something to load. • Backups keep your presets' background textures, and a failed restore says what went wrong. • Launch is quicker.
